ALTY takes a broad, multi-asset approach in its quest for income. The portfolio breaks down into five buckets: infrastructure (MLPs, infrastructure-themed equities), and ETFs with exposure to real estate (via SRET), preferreds (via PFFD), emerging market bonds (via EMBD) and covered calls (via QYLD). The infrastructure bucket has 16 companies, 8 representing MLPs and 8 for US infrastructure. They are selected for high trailing dividend yield and low trailing volatility. The index caps each asset class at 20%, and then within each asset class the constituents are equally weighted. The index is reconstituted annually, but may rebalance quarterly if the weight of any buckets deviates more than 3% from its target. Prior to Sep 28, 2021, ALTY was known as the Global X SuperDividend Alternatives ETF, its previous strategy focused dividends in the selection process and weighted for equal risk contribution based on trailing volatility.
